DIMENSIONLESS RELATIVE WAVE CELERITY VS DIMENSIONLESS
WAVENUMBER IN SHALLOW WAVE PROPAGATION IN OPEN CHANNEL FLOW (Ponce and Simons, 1977) |
[ To the left the celerity is asymptotic to the relative kinematic wave celerity (Seddon celerity: 0.5, for Chezy friction in hydraulically wide channel). To the right, the celerity is asymptotic to the relative dynamic wave celerity (Lagrange celerity: 1/ Fr). For each curve, the point of inflection in the middle corresponds with maximum wave attenuation. Wave attenuation is minimized at both extremes of the dimensionless wavenumber spectra. ] |
